Panic Disorder

There is no single known cause for panic disorder; rather, it is believed to result from a combination of biological, genetic, and environmental factors. The biological theory suggests that some individuals have a 'hypersensitive' nervous system that overreacts to physiological changes. For example, a slight increase in heart rate from caffeine might be interpreted by the brain as a life-threatening emergency, triggering a full panic response.

Non-modifiable

• Genetics: Having a first-degree relative (parent or sibling) with panic disorder significantly increases the risk.
• Sex/Gender: Women are diagnosed at a much higher rate than men.
• Brain Structure: Differences in the volume or activity of the amygdala and other limbic system structures.

Modifiable

• Stressful Life Events: Major life transitions, such as a death in the family, divorce, or job loss, can trigger the onset.
• Smoking and Caffeine: High intake of nicotine or caffeine can increase physiological arousal and trigger attacks in vulnerable individuals.
• Substance Use: Withdrawal from certain substances or the use of stimulants can provoke panic symptoms.
• Childhood Trauma: A history of physical or sexual abuse is a significant risk factor.

Individuals in their early 20s are at the highest risk for the initial onset of panic disorder. Those with other existing mental health conditions, particularly generalized anxiety disorder (GAD) or major depressive disorder, are also at increased risk. Additionally, people with certain medical conditions, such as mitral valve prolapse or asthma, may have a higher predisposition to panic symptoms.

While you cannot change your genetic makeup, certain strategies may help prevent the development or worsening of the disorder:

• Early Intervention: Seeking help at the first sign of recurring panic attacks can prevent the development of agoraphobia.
• Stress Management: Developing healthy coping mechanisms for life stress.
• Avoidance of Stimulants: Limiting caffeine and avoiding nicotine can reduce the baseline of physical anxiety.
• Screening: Routine mental health screenings during primary care visits can identify at-risk individuals early.

The diagnostic journey usually begins with a visit to a primary care physician to rule out underlying physical conditions. Because panic symptoms are so physical, many patients undergo extensive cardiac or neurological testing before a psychological cause is identified.

A healthcare provider will perform a thorough physical exam, checking the heart rate, blood pressure, and lung sounds. They will look for signs of other conditions, such as tremors that might suggest a thyroid issue or irregular heart rhythms.

While no blood test or scan can 'see' panic disorder, tests are used for differential diagnosis:

• Electrocardiogram (ECG/EKG): To rule out heart arrhythmias or other cardiac issues.
• Blood Tests: Specifically a Thyroid Function Test (to rule out hyperthyroidism) and a Complete Blood Count (CBC).
• Toxicology Screen: To determine if caffeine, medications, or illicit substances are contributing to the symptoms.
• Imaging: In rare cases, an MRI or CT scan may be ordered if neurological symptoms are atypical.

According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders), a diagnosis of panic disorder requires:

1. 1Recurrent, unexpected panic attacks.
2. 2At least one of the attacks has been followed by one month or more of:

• Persistent concern or worry about additional panic attacks or their consequences (e.g., losing control, having a heart attack).
• A significant maladaptive change in behavior related to the attacks (e.g., avoiding exercise or unfamiliar situations).

Healthcare providers must distinguish panic disorder from:

• Social Anxiety Disorder: Where panic only occurs in social situations.
• Post-Traumatic Stress Disorder (PTSD): Where panic is triggered by trauma reminders.
• Hyperthyroidism: An overactive thyroid can mimic panic symptoms.
• Cardiac Arrhythmias: Such as SVT (Supraventricular Tachycardia).

The primary goals of treatment are to reduce the frequency and intensity of panic attacks, eliminate the fear of future attacks, and resolve any avoidance behaviors (agoraphobia). Successful treatment allows the individual to return to their baseline level of functioning in work and social environments.

The standard initial approach for panic disorder is a combination of Cognitive Behavioral Therapy (CBT) and medication. CBT is highly effective; it helps patients understand that panic symptoms are not dangerous and teaches them how to manage physical sensations through exposure and cognitive restructuring.

Several classes of medications are used to manage panic disorder. Talk to your healthcare provider about which approach is right for you.

• Selective Serotonin Reuptake Inhibitors (SSRIs): These are typically the first-line medication choice. They work by increasing the levels of serotonin in the brain, which helps regulate mood and anxiety. They are preferred due to their safety profile and effectiveness in long-term prevention.
• Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): These work similarly to SSRIs but also affect norepinephrine. They are often used if SSRIs are not fully effective.
• Benzodiazepines: These are central nervous system depressants that work quickly to calm physical symptoms. While highly effective for acute relief, they are generally used for short durations or 'as needed' due to the risk of dependence and tolerance.
• Tricyclic Antidepressants (TCAs): An older class of antidepressants that can be very effective for panic disorder, though they may have more side effects than SSRIs.
• Beta-Blockers: While not a primary treatment for the disorder itself, these may be used to manage specific physical symptoms like a racing heart in certain situations.

If first-line treatments are unsuccessful, healthcare providers may consider switching medication classes or combining therapy with different types of medications. Monoamine Oxidase Inhibitors (MAOIs) are sometimes used in treatment-resistant cases, though they require strict dietary restrictions.

• Cognitive Behavioral Therapy (CBT): Specifically 'Interoceptive Exposure,' where patients are safely exposed to the physical sensations of panic (like increased heart rate) to desensitize them.
• Applied Relaxation: A technique involving muscle relaxation exercises to reduce physical tension.
• Biofeedback: Using sensors to help patients gain voluntary control over physiological functions like heart rate.

Medication is typically continued for 6 to 12 months after the panic attacks have stopped to prevent relapse. Regular follow-up appointments are necessary to monitor side effects and adjust dosages. Therapy may last for 12 to 20 weekly sessions, though some patients benefit from 'booster' sessions later on.

• Pregnancy: Many anxiety medications carry risks during pregnancy. Treatment plans must weigh the risks of the medication against the risks of untreated severe anxiety for both the parent and the fetus.
• Elderly: Older adults may be more sensitive to the side effects of medications (especially benzodiazepines) and often require lower starting doses.
• Children: Treatment focuses heavily on family-based CBT, with medications reserved for severe cases.

Dietary choices can significantly influence the nervous system's baseline arousal level.

• Avoid Stimulants: Caffeine (coffee, tea, soda, energy drinks) is a known trigger for panic attacks.
• Limit Alcohol: While alcohol may feel calming initially, 'rebound anxiety' during the detoxification process can trigger severe attacks.
• Blood Sugar Stability: Eating regular, balanced meals helps prevent hypoglycemia (low blood sugar), which can mimic the shakiness and dizziness of a panic attack.

Regular aerobic exercise (such as brisk walking, swimming, or cycling) has been shown to reduce anxiety. It helps the body 'burn off' excess adrenaline and trains the brain to associate a fast heart rate with a safe activity rather than a panic attack. However, some individuals may need to start slowly if a high heart rate is a psychological trigger.

Sleep deprivation is a major trigger for anxiety. Maintaining a consistent sleep-wake cycle, keeping the bedroom cool and dark, and avoiding screens an hour before bed can improve sleep quality and emotional resilience.

• Diaphragmatic Breathing: Learning to breathe from the belly rather than the chest can physically signal the nervous system to calm down.
• Mindfulness Meditation: Helps individuals observe their thoughts and physical sensations without reacting to them with fear.

Some patients find relief through yoga or acupuncture. While some herbal supplements (like lavender or chamomile) may promote relaxation, others can interact dangerously with prescribed medications. Always consult your doctor before starting any supplements.

• Stay Calm: Your calm demeanor can help ground the person having an attack.
• Don't Minimize: Avoid saying 'just relax' or 'there's nothing to worry about.' Instead, say 'I know this feels scary, but you are safe and this will pass.'
• Encourage Treatment: Gently support your loved one in seeking and sticking to a professional treatment plan.

The prognosis for panic disorder is generally excellent with appropriate treatment. Most individuals see a significant reduction in the frequency of attacks within weeks of starting therapy or medication. Research suggests that up to 70% to 90% of people experience substantial improvement, and many achieve full remission.

If left untreated, panic disorder can lead to:

• Agoraphobia: Becoming unable to leave the home or enter public spaces.
• Substance Use Disorders: Attempting to 'self-medicate' with alcohol or drugs.
• Depression: Chronic anxiety often leads to secondary clinical depression.
• Suicidal Ideation: The distress of the condition can lead to feelings of hopelessness.

Panic disorder is often a chronic condition that may wax and wane. Long-term management involves staying aware of 'early warning signs' and utilizing the tools learned in therapy. Some individuals may require long-term, low-dose medication to maintain stability.

Many people live full, productive lives by managing their condition. Joining a support group can reduce the shame and isolation often associated with the disorder. Sharing experiences with others who understand the physical reality of a panic attack can be incredibly healing.

You should contact your healthcare provider if:

• Your panic attacks increase in frequency or intensity.
• You find yourself avoiding more places or activities.
• You experience side effects from your medication that interfere with daily life.
• You feel that your current treatment plan is no longer effective.
